Pool Wave Generator

ABSTRACT

A pool wave generator is disclosed having a pool area and a plurality of chambers for generating a wave in the pool area. Exemplary embodiments described herein may be used to control the fluid flow within the pool area. For example, exemplary embodiments may include oblique angled lateral side walls on opposing sides of the wall comprising the plurality of chambers. Exemplary embodiments may also include one or more additional water structures for receiving, controlling, and/or directing water generated from a wave. The water structures may be configured to reduce an amount of water directly returning into the water at the same location as it exits thereby minimizing currents back into the water toward the plurality of chambers.

PRIORITY

This application claims priority to PCT Application No. PCT/CA2021/000045, filed May 18, 2021 and U.S. Provisional Patent Application No. 63/026,508, filed May 18, 2020, both of which are incorporated into its entirety herein.

BACKGROUND

Water attractions have brought fun to different people from different geographic locations for many generations. The water attraction permits different geographic areas to have access to simulated experiences from other geographic areas. For example, a wave pool may approximate an experience at a beach.

Different water attractions may be used to approximate natural environments to permit users to experience sports and activities from these other environments. For example, sheet wave rides simulate a surfing or boogie boarding experience that permits a rider, with their body or a thin board, to ride upon a sheet flow of water that is contoured by an underlying ride surface. The sheet wave ride does not provide a true surfing experience, as the sheet flow does not permit wave breaking or the use of an actual surfboard.

Deep wave surfing systems are provided that attempt to create a more accurate approximation of the surfing experience in the natural environment. United States Patent Number (USPN) 8,434,966; U.S. Pat. Nos. 9,103,133; 9,279,263; 10,145,135; 10,280,640; and 10,526,806 disclose deep wave surfing simulators, each of which is incorporated by reference in their entirety herein.

Deep wave rides pose a unique challenge to manage the vast amount of water that is used in the ride. For example, currents and eddy current may form that can undermine the wave formation.

SUMMARY

A pool wave generator is disclosed having a pool area and a plurality of chambers for generating a wave in the pool area. The plurality of chambers may be used to retain or release water into the pool to create a desired wave.

Exemplary embodiments described herein may include unique pool configurations for managing water flow to influence currents. Such exemplary configurations may be useful in creating and maintaining desired wave formations and/or in permitting repeated wave formations either in a series along a length of a pool or in time to minimize elapse time between wave formations. Exemplary embodiments may therefore include a lagoon and/or trough at a shallow end of a pool in order to direct water at the end of a wave. The lagoon and/or trough may be used to absorb and/or dissipate currents within the pool. In an exemplary embodiment, the pool may be configured with an upward tapering floor to generate a beaching area. The lagoon and/or troughs may be configured relative to the shallow area of the beaching area such that wave energy flushes over the high tide line of the beaching area and into the lagoon and/or trough to dissipate the wave energy and resulting currents. The lagoon and/or trough may be configured to reintroduce the captured water back into the pool and/or chambers. The troughs may be covered and/or uncovered.

DESCRIPTION

The following detailed description illustrates by way of example, not by way of limitation, the principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention. It should be understood that the drawings are diagrammatic and schematic representations of exemplary embodiments of the invention, and are not limiting of the present invention nor are they necessarily drawn to scale.

Exemplary embodiments described herein include a pool configured to create waves. The pool may include one or more chambers at one end that are configured to receive and release water into the pool for generating the waves. Exemplary chambers are provided to reduce turbulence and generate better waves for riding. The pool may be configured to generate zones that define or generate waves of different profiles and/or for riding by riders of different experience levels. The pool may also be configured, either in the floor configuration and/or in the inclusion of additional water features such as lagoons and/or channels for controlling water flow to dissipate wave energy and control water currents.

Although embodiments of the invention may be described and illustrated herein in terms of a pool wave generator having unique and novel features, it should be understood that embodiments of this invention do not require or necessitate the inclusion of each of the features. The instant disclosure does not require any specific component, configuration, or feature, and any combination of features may be incorporated or combined and remain within the full description of the invention. For example, the inclusion of the elongated chamber between the chamber and the pool to reduce eddy currents may be used in any conventional features of a pool wave generator. Similarly, the inclusion of the spectator area, and/or the bottom contour to generate different wave zones may similarly be used alone or in conjunction with other features described herein.

FIG. 1A illustrates and exemplary wave pool according to embodiments of the invention. The exemplary pool wave generator 10 ay include a pool area 12 and one or more chambers 14 for generating a wave within the pool area. The wave 16 may propagate away from the chamber(s) 14 and toward a terminal end 18 of the pool.

In an exemplary embodiment, the pool area 12 may be a recessed pool configured to hold water. The terminal end 18 may be a wall for retaining the water. The wall may be vertical or may be sloped. In an exemplary embodiment, the terminal end is created by a sloped bottom of the pool to approximate or similar a beach area. As the water is pushed across the pool area 12 by the release of water from the chambers 14, the water may travel toward the terminal end and travel across and up the sloped bottom until the water stops and eventually comes back to the pool area along the sloped bottom under the influence of gravity.

FIG. 1A illustrates an exemplary pool wave generator that comprises two sides in which a wave may be propagated from the chambers toward opposite ends of the pool. This may be used to create different areas that may have similar or different wave profiles for use by different riders. The different areas may be used to create waves for rider having levels of experience. Exemplary embodiments include a pool wave generator in which a wave is propagated in a single direction, such as illustrated in FIG. 1B.

As represented by the arrows adjacent the chambers 14, the chambers 14 may release water into the pool area 14 sequentially. The chambers may be linearly aligned along one side of the pool 12. The chambers may also include different directions, configurations, and orientations. The release of water from the chambers may be used to control wave attributes, such as a wave height, direction, shape, etc. As illustrated, chambers toward the middle of the plurality of chambers are released together and then the chambers may release sequentially moving outward toward opposing ends of the plurality of chambers. The chambers may also be configured to release in different directions or sequence, such as from one end to the other or from opposing ends toward the middle of the plurality of chambers.

FIG. 1A illustrates an exemplary embodiment in which a linear arrangement of chambers is provided along one edge of the pool area 12. The chambers may traverse an entire length of the edge of the pool. As illustrated, projecting immediately from the end of the last chamber on the edge of the pool, a lateral side of the pool wall 19 may extend at a non-zero angle measured from the linear extension of the edge of the pool defined by the chambers. In other words, the lateral wall may immediately extend forward from the end of the chamber. The lateral wall may also have a component that extends outward in a continued extension of the chamber linear direction, thus forming a non-zero, non-perpendicular angle with the linear extension of the pool edge comprising the chambers. Angling the pool wall may reduce the amount of water required to fill a pool, and reducing the areas of the pool that may produce less desirable wave action.

FIG. 1C illustrates an exemplary vector modelling of speed of the water and corresponding waves during wave generation of an exemplary wave pool generator according to embodiments described herein. As illustrated, defined wave areas can be seen as the wave traverses the length of the pool. As illustrated by the dotted box in the middle of the pool area, the pool may include a dead spot that can be used as a paddling channel and/or waiting zone to enter the wave areas.

Angling the opposing lateral sides may also be used to control the currents of the pool according to embodiments described herein. FIG. 1D illustrates an exemplary wave water velocity map with a pool have an extending wall at opposing ends of the pool wall comprising the chambers. As illustrated, the pool experiences significant return currents towards the flat wall. This creates a vortex at the end of the chambers that can interfere with wave propagation. FIG. 1E illustrates an exemplary wave water velocity map with a pool having angled walls according to embodiments described herein. Unexpectedly, the removal of the water flow path back to the chambers lessens the resulting vortex at the end of the chambers. It is believed that the angled wall focuses the remaining wave energy, which can then be used for creating an intermediate wave riding area according to embodiments described herein. The wave water velocity map illustrates the velocity of water during the wave generation, with the arrow representing the direct and quantity (a larger area represents a greater velocity or faster wave).

Exemplary embodiments described herein may include a pool having a first linear edge in which a plurality of chambers are configured to fluidly couple and dispense water into the pool along the first linear edge. One or more chambers may be configured along an entirety of the first linear edge. The pool may include two opposing lateral sides extending from terminal ends of the first linear edge. The opposing lateral sides may extend forward of the first linear edge at an angle. The angle of each lateral side may be the same or different, depending on the pool configuration. The opposing lateral sides may extend outward and forward from the first linear edge at an oblique angle. Exemplary embodiments of the angled opposing lateral sides may assist in current mitigation. Exemplary embodiments of the angled opposing lateral sides may also focus a wave's energy such that a wave may be reformed for different experience levels.

FIGS. 2A-2C illustrate an exemplary wave generating chamber and associated control thereof to generate a wave in the wave pool described herein. The chamber 20 may be configured to retain water at a chamber water level 28 that when released into the pool, a pool water level 26 is increased creating a wave 26′ that propagates away from the chamber 20, across the pool. The chamber may include one or more valves 22, 24 for controlling the retention and release of the water within the chamber. In an exemplary embodiment, a first valve 22 may control the water flow into and out of the chamber 20. In an exemplary embodiment, a second valve 24 may control air or fluid flow into and out of the chamber 20. The second valve 24 may be used to introduce pressurized gas into the chamber and/or to vent gas from the chamber to assist in the movement of the water into and out of the chamber.

As seen in FIG. 2A, the system may have been released so that no water is in the chamber 20 or the water level 28 in the chamber is at a low level (such as illustrated in FIG. 2C). The second valve 24 may be opened to purge air from the chamber. The chamber may be configured to evacuate air from the chamber 20, such that the chamber is negatively pressurized. The vent 24 may also be open, such that the chamber 20 is at neutral pressure and the air in the chamber is permitted to vent as the chamber is filled with water. The first valve 22 is opened and the rush of water into the chamber elevates the water level in the chamber.

As seen in FIG. 2B, the first vent 22 is closed to retain the chamber water level 28 at a height greater than the pool water level 26. The chamber may then be filled with a pressurized gas to impose additional pressure on the water within the chamber. The second valve 24 is then closed and the first valve is then opened.

As seen in FIG. 2C, the pressurized air in the chamber pushes the water level 28 within the chamber, which in turn surges water out of the chamber to generate a wave 26′ the propagates across the pool. The first valve 22 may be closed while the air in the chamber is vented, such as through the second valve 24. The first valve 22 may be closed to limit the amount of water back into the chamber to minimize disruption to the formed wave 26′. The first valve 22 may also remain open to permit the water to return to the chamber and be closed is discussed with respect to FIG. 2B.

In an exemplary embodiment, the system is configured to cycle through the process of releasing water from the chamber and permitting the resurgence of water into the chamber. The system may also include a delay after any number of cycles to permit the water in the pool to settle and reduce turbulence that could affect wave generation.

In the exemplary embodiment provided, two valves are illustrated—a first valve 22 for water control and a second valve 24 for gas control. Any combination of valves may be used and are within the scope of the instant disclosure. For example, multiple gas valves may be used to vent the chamber, inject pressurized gas, etc., and multiple fluid valves may be used to emit or retain the water within the chamber. The order and/or cycle of the valves as described herein is exemplary only. Any number of different ways may be used to release the wave using valves, gates, or other methods. The valves may be opened, closed, in different ways. For example, the system may use a purge system to remove gas from the chamber before resurgence of water to elevate the water level returning to the chamber. For example, the system may not use a pressurized gas system for expelling the water into the pool. For example, single direction valves may be used such that valves do not necessitate individual actuation to open and close. The valves of each chamber may be controlled individually or as a sequence within a larger operation of the entire pool system.

FIG. 3 illustrates as exemplary wave pool 30 for generating different zones having different wave characteristics according to embodiments of the invention. In an exemplary embodiment, the pool profile 32 and the pool floor 34 may be contoured to define a desired wave profile and/or to create multiple wave zones 36, 37, and 38.

In an exemplary embodiment, multiple wave zones 36, 37, 38 may be created. The creation of multiple wave zones may be generated from a single wave generation cycle of the chambers. For example, the chambers may release in sequence to form a first wave. That first wave may change profile, height, direction, etc. The wave may also deteriorate and/or reform based on the underlying topography of the pool floor. As illustrated, three wave zones are generated for a single wave generation cycle on one side of the pool. The pool may have a mirror configuration, such that the entirety of the pool has six wave zones. However, three of the wave zones are independent from another three of the wave zones since a different wave or portion of the wave creates the first three wave zones than the wave or another portion of the wave that creates the second three wave zones. Any combination of wave zones may be generated and the combination of two sides of three for a total of six zones is illustrative only. In an exemplary embodiment, the wave pool may have only one, two, three, or more wave zones. The pool may have a mirrored configuration such as in FIG. 1A, thereby doubling the wave zones or the pool may be a single side as in FIG. 1B. The opposing sides of the pool may also be configured differently, such that different wave zones may be created across the entirety of the pool.

As illustrated, a first wave zone 36 is adjacent the wave generating chambers. The wave at this portion is at its highest. This area may be for the most experienced riders. It may also be for the short board riders.

As illustrated, a second wave zone 37 may be in an area of the pool after the wave leaves the chambers that runs along a sidewall or edge of the pool. The wave will dissipate energy and reduce height after the wave propagates away from the chambers. This area is therefore created for intermediate riders and longboard riders.

As illustrated, a third wave zone 38 may be adjacent the side of the pool away from the chambers. The edge may correspond to a shore area 46′ of the pool. This area may have a shallow depth and may have an inclined floor bottom. The first wave zone 38 may be for beginning wave riders. This area may also be used for boogie boards, foam boards, kayaks, or skimming boards. This area may also be used for body riding or wave jumping.

The bottom of the pool may have areas that correspond or influence the wave zones. For example, a first area 42′ of the pool bottom may generally correspond to the first wave zone 36, while a second area 44′ of the pool bottom may generally correspond to the second wave zone 37, and a third area 46′ of the pool bottom may generally correspond to the third wave zone 38. A fourth area 44′ and/or other areas may be used to generate and separate the different wave zones and/or be used to reform waves as the wave propagates from the chambers. The different areas of the pool floor are discussed more fully with respect to FIG. 4 .

The different floor bottom areas may be used to influence a wave profile. For example, the depth of the floor may influence a wave size, while the slope of the floor may affect the wave shape. The first area 42′ adjacent the chambers may therefore generate a wave zone 36 for the most experienced riders. This area may be approximately 2-6 meters deep. This area may therefore have a floor bottom with a greater slope or incline toward the shore or opposing side of the pool and/or may have the greatest depth. The third area 46′ may be adjacent the short or edge of the pool away from the chambers and may generate a wave zone 38 for the most inexperienced riders. This area may therefore have a floor bottom with the smallest slope or incline toward the edge and/or may have the shallowest depth. The gentler slope may make the wave brake softer.

In an exemplary embodiment, the edge of the pool away from the chambers may also be contoured to influence the wave characteristics. For example, in the area of the third wave zone, or the area for beginners, the edge may be elevated toward a middle of the pool, on an opposite side of the pool from the middle chambers of the sequence of chambers. This elevation may form a shore or dry indentation into the side of the pool. As the wave propagates across the pool from the chambers toward the shore, the wave may wrap around the elevation extending into the pool area. Other or additional elevations may be provided along the short to create additional wave zones. In an exemplary embodiment, an elevation may be used to separate and/or redirect a wave.

As illustrated, the chambers may release water into the pool in sequence generating a wave. If the chambers first open at the middle of the sequence of chambers and then open sequentially in opposing directions toward each end, both left and right waves will propagate from the chambers and break at approximately the same time. The chamber sequencing may also be delayed or offset, such that the left and right breaking waves may be staggered. The expert wave zone may be defined as an area adjacent or proximate the chambers. The wave within the expert wave zone may break along the wave-generating wall. The wave may retain an approximate constant height as the sequential release of water from the chambers may be used to maintain the wave formation. In an exemplary embodiment, the wave height in the expert wave zone may be approximately 1.5 to 3.5 meters. After the wave leaves the area proximate the chambers, the wave will dissipate energy and the wave height will decrease. The wave extending along the side edge of the pool away from the chambers may form the intermediate wave zone with a wave height that is reduced from the expert wave zone. In an exemplary embodiment, the wave height in the intermediate wave zone may be approximately 1-2 meters. The wave height may continue to decrease as it travels away from the chambers. The wave may thereafter break along the opposite side of the pool in the shallow are to create a bigger wave zone. In an exemplary embodiment, the wave height in the beginning wave zone may be approximately 0-1.5 meters.

FIG. 4 illustrates an exemplary bottom profile corresponding to the different wave zones described in FIG. 3 of a pool wave system 40. FIG. 5A is the illustration of the exemplary bottom profile of FIG. 4 with a reference line 50. FIG. 5B illustrates the cross sectional perspective along the reference line 50 of FIG. 5A to illustrate the pool floor. As illustrated, the bottom profile may include at least three areas.

In an exemplary embodiment, a first area 42 may correspond to the area proximate the chambers 14. As seen in FIG. 5B the pool floor 52 of this area may include a gradual slope upward such that the pool adjacent the chamber is deeper than the pool on an opposing side of the area 42 from the chamber. The slope may traverse from deeper to shallower moving across the area away from the chambers at an angle α. The first area 42 may be generally rectangular and extend directly in front of the chambers as illustrated in FIG. 4 . The first area 42 may also be flared at the ends such that the area traverses in front of the chambers and as the area slopes away from the chambers extends outward past the ends of the chambers, as illustrated in FIG. 3 . Other shapes of this area are also contemplated.

In an exemplary embodiment, a third area 46 may correspond to the area on an opposite end of the pool form the chambers 14. The third area 46 may be on a side of the pool corresponding to an end of the wave travel that is opposite from the origin of the wave. The pool floor 56 of this area may have a more gradual slope than the slope of the area adjacent the chambers. The pool floor 56 may include a gradual slope upward such that the pool toward the first area 42 is deeper than the area on an opposite side thereof. The terminal end of this area may have a zero depth such that the water washes up the side to the surface of the water. This area may approximate a beaching area. The slope may traverse from deeper to shallower moving across the area in a direction away from the chambers at an angle β. This area may correspond to a band or width at the terminal end of the wave at an opposing side of the pool from the chambers. As the chambers may generate a wave that propagates away from the chambers in an oblique angle and not directly perpendicular to the chambers, the opposing end of the pool may be offset and include a portion of the pool that ends past the lateral end of the chambers. Opposite may therefore include directly or geometrically opposite as well as opposite based on the propagation of the wave generated from the chambers.

As illustrated, the third area 46 may be shaped in a curve such that portions of this area are further away from the chambers than other portions of this area. For example, the shore area 46′ may be curved such that portions adjacent the lateral side of the pool corresponding to the ends of the chambers and toward a middle of the shore (for a mirrored pool) or the opposite lateral side of the pool (for a single sided pool) are positioned closer toward the chambers than areas there between. As illustrated, the shore region or the side of the pool opposite the chambers may therefore include three curved regions, two outside regions on opposing ends of the shore region in which the region is concave with the inward concavity toward the chambers, and an interior curved region between the two outside regions in the middle of the shore region is convex with the outward concavity toward the chambers.

As illustrated, a second area 44 may extend from the first area 42 to the third area 46. This area may be similarly sloped. The slope of the area may be linear, curvi-linear, or curved. This area may include a gradual slope that transitions the bottom surface from the first area 42 to the third area 44. This area may also be contoured to provide a transition to any other area that may be included in the bottom profile. The second area 44 may therefore provide a transitional surface between two or more other floor bottom surfaces or areas.

The pool may include one or more other floor areas defining one or more other zones. For example, the first wave zone may be separated from the third wave zone. The separation may be to create a floor profile to recreate a desired waveform. The separation may be to permit space between the various wave zones for rider safety and/or rider enjoyment. As seen in FIGS. 3, 4, and 5 , a transition area 48, 48′ may be used. The transition area 48, 48′ may correspond to floor bottom 88 that is generally flat. The transition area may be positioned between the first area 42 and the third area 46 and/or the shore area. As illustrated in FIG. 3 , the first area 42′ may contact the third area 46′ in a middle portion of the pool, while the transition section 48′ separates the first area 42′ from the third area 46′ toward outer lateral sides of the pool adjacent the second area 44′. In an exemplary embodiment, such as illustrated in FIG. 4 , the transition area 48 may separate the first area 42 from the third area 46 along a length of the pool, such that the first area 42 does not contact the third area 46.

In an exemplary embodiment, the gradient of the pool floor bottom 52 corresponding to a first area 42, 42′ is greater than the gradient of the pool floor bottom 56 corresponding to the third area 46, 46′ (α>β). In an exemplary embodiment, the gradient of the pool floor bottom of the second area 46, 46′ is generally equal to either of or between the gradient of the first area and the second area (α≥θ≥β). The pool floor bottom 52 may have a slope of between 3 and 10 degrees. The pool floor bottom 56 may have a slope of greater than 0 degrees to 5 degrees. The pool floor bottom corresponding to the second area 46, 46′ may have a slope of between 2 and 10 degrees.

The configuration, shape, elevation, slopes, and other features of the pool floor bottom described herein are exemplary only. Other or additional features may be added and are within the scope of the present description. For example, an additional sloped floor and/or one or more other level floor areas may also be included to create additional wave areas and/or separate wave areas. Other elements may also be included, such as floor configurations, walls, dividers, elevations, shore features, etc. to further enhance the surfing experience or to provide additional benefits to the pool wave generator described herein. These may include features for splitting, redirecting, reforming, or otherwise effecting the generated wave.

FIG. 6 illustrates an exemplary wave-generating chamber according to embodiments of the invention.

Conventional chamber configurations in which the chamber and pool share a common wall or in which the chamber and the pool are in close proximity create eddy currents through the area between the chamber and the pool. The eddy currents may interfere with the shape and stability of the generated wave. U.S. Pat. No. 10,526,806 discloses a vane positioned between or near the chamber and pool interface to control and direct the water movement and reduce the formation of eddy currents. Such systems create construction and maintenance costs as the vanes must be internally supported and maintained. Exemplary embodiments describes herein permit the formation of a wave pool that may manage or reduce the formation of eddy currents without the use of a vane or an internal structure within or adjacent the water flow path between the chamber and pool.

The chamber 62 and the configuration of the chamber 62 to the pool 64 may be used to generate waves of desired characteristics. Exemplary embodiments use the chamber width CW and the width between the pool and the chamber (wall width) WW. In an exemplary embodiment the width between the pool and the chamber, WW, is greater than 2 meters. The greater distance in this transition area between the chamber and the pool, however, can affect and reduce the height of a generated waved. Therefore, conventionally, it was desirable to keep this area as short as possible. This distance, however, can be used to reduce turbulence and create a better wave profile. In an exemplary embodiment, the distance between an edge of the pool and an edge of the chamber is between 2 and 7 meters. The chamber width, CW, may influence the resulting height of the generated wave. Similar to the wall width WW, this dimension conventionally was reduced as the additional width necessitated additional power for controlling and releasing the wave. For example, additional gas would be needed to create the same pressure on the water surface. The chamber width CW is preferably 1.3 to 5 meters.

In an exemplary embodiment, the chamber 62 may be coupled to the pool 64 by a passage 66. The passage may be positioned at a depth lower than the pool 64, such that water exits the chamber and enters the pool, on a bottom of the pool or adjacent to the bottom of the pool. The passage may be shaped such that the direction of water leaving the passage may have a vertical component. The passage may include an inner wall 68B and an outer wall 68A. The inner wall 68B and outer wall 68A may be curved to reduce turbulence imposed on the water as it passes through the passage from the chamber to the pool.

FIG. 7 illustrates an exemplary cross sectional profile of a wave pool according to embodiments of the invention. The exemplary wave pool 70 may include any combination of features as described herein. For example, the system may include a pool 64 having a pool floor. The pool floor may have one or more different areas such as first sloped area 52 adjacent chamber 62, that transitions through a generally flat transition area 54 to a third sloped area 56. The chamber 62 may control the egress and ingress of water to and from the chamber through one or more valves 22, 24 as described herein.

As described herein, the terminal end of the pool 64 toward the chamber may be separated by the chamber by a width WW. In an exemplary embodiment, the separation between the chamber and the pool may permit spectator observation. As illustrated, the space between the pool 64 and the chamber 62 includes a floor 78 in which an observer may stand. The floor may be positioned around the water height of the pool 64 or positioned higher to provide better viewing of a rider in the area adjacent the chambers or in the rest of the pool. This area may include bleachers 76 or other sitting area or walkway to permit pedestrians and/or observers to pass by or observe the action within the pool.

In an exemplary embodiment, the separation between the chamber and the pool may permit storage of system components in addition to or in place of spectator observation. For example, the area between the pool 64 and the chamber 62, positioned over passage 66, may include the space for the air plenum, pump equipment, blowers, electronics, controllers, equipment room, or other system components. As illustrated, the bleacher or sitting area may incorporate an equipment room 86. The space under the floor 78 or otherwise positioned between the chamber and the pool may include other component parts, such as a space for the air plenum, electronics, controllers, or other equipment. As illustrated, the area between the pool and chamber includes a space for the air plenum 84 and behind the chamber 86 is positioned the electrical room.

In an exemplary embodiment, the space between the pool 64 and the area 72 between the pool and the chamber 62 may be open and/or unobstructed. In this case, a rider, swimmer, and/or lifeguard may be able to enter the pool area from the floor 78 on the wave generating side of the pool. In an exemplary embodiment, a wall 74 may extend beyond the height of the water to separate the space between the pool and the chamber from the pool itself. The wall 74 may be an extension of the side of the pool over the passage entrance. The wall 74 may be of an acrylic, plastic or other semi-transparent or transparent material to permit observation of the activities within the pool at a location outside of the pool. The wall 74 may protect observers from getting wet or accidentally falling into the pool.

Exemplary embodiments described herein may include unique pool configurations for managing water flow to influence currents. Such exemplary configurations may be useful in creating and maintaining desired wave formations and/or in permitting repeated wave formations either in a series along a length of a pool or in time to minimize elapse time between wave formations. Exemplary embodiments may therefore include a lagoon and/or trough at a shallow end of a pool in order to direct water at the end of a wave. The lagoon and/or trough may be used to absorb and/or dissipate currents within the pool.

As previously described with respect to FIG. 1A, an exemplary wave pool generator may include a pool area and one or more chambers for generating a wave within the pool area. The wave 16 may propagate away from the chamber(s) and toward a terminal end of the pool. The terminal end of the pool may be created by a sloped bottom of the pool to approximate a beaching area. As the water is pushed across the pool area by the release of water from the chambers, the water may travel toward the terminal end and travel across and up the sloped bottom until the water stops and eventually comes back to the pool area along the sloped bottom under the influence of gravity. However, the water return into the pool may create currents that interfere with repetitive wave generation. Exemplary embodiments may therefore include additional water features to handle the water movement.

FIG. 8 illustrates an exemplary embodiment of a wave pool with a pool area 181 and one or more chambers 14 to generate a wave 182 moving from the chambers to a shore area 185. The shore area may be created by an upwardly taper pool floor such that the water level of the pool area 181 and the pool floor meet. The incoming wave 182 may push water up on the beaching area 185, such that the location the water meets the shore varies with the progression of a wave. The shore area 185 may therefore include a high water line 184 which may be the highest level (or further away from the chambers) the water can reach on the beaching area 185 under a given wave progression. The high water line 184 may depend on factors of the wave generating device, including chamber release timing, pressure within the chamber, etc. A low water line may be the location along the beaching area 185 in which the water naturally rests against the pool floor without a wave or the lowest location (closest to the chambers) that the water rests when waves are being generated.

Exemplary embodiments described herein may include a lagoon and/or trough in which the pool floor reaches a highest position in the beaching area 185. The floor may thereafter recede or become lower such that water may be captured in a second pool area 183. The second pool area 183 may be shallow to create a wading pool or lagoon or may be deeper to create a trough or trench to direct water. The second pool area 183 may be used to capture water from the pool area 181 from waves 182 traversing the beaching area 185 and into the second pool area 183. This water capture may reduce the water returning to the pool area 181 and reduce adverse impacts from currents generated from the receding water.

The highest point of the beaching area before transitioning into the second pool area 183 may occur between a low water line and high water line of pool area 181, adjacent the low water line, at the low water line, or combinations thereof along the beaching area. For example, as illustrated, the highest point of the beaching area on the lateral outer edges of the beaching area 185 may be adjacent or within the low water line, such that the pool area 181 and the second pool area 183 may be in fluid communication regardless of the generation of a wave. The highest point of the beaching area toward the central area of the pool may be outside or at the high water line 184 such that the pool area 181 and second pool area 183 are separated by a gap 186 of an elevated floor such that the pools are not in fluid communication through the gap (but may be through other areas along the beaching area). The highest point of the beaching area may also be between the low water line and high water later, such that the pool area 181 and second pool area 183 are in fluid communication along the portion of the beach area only when a wave is generated and propagates through the beaching area. In this case, the water is captured as it is pushed up on the shore and does not return to the pool area 181 directly from the exit location.

As illustrated in FIG. 8 , a combination of the relative locations and separation of the first pool area 181 form the second pool area 183 may be used. As illustrated, the first and second pool area may be in fluid communication during the generation of a wave along a length of the beaching area from an outside lateral edge toward the middle of the beaching area. The highest elevation of the pool floor between the first pool area 181 and the second pool area 183 may be approximately equal to the low water line or between the low water line and the high water line. Toward a center of the pool area the first pool area 181 may be separated with a gap 186 from the second pool area 183 such that the highest elevation of the pool floor between the first pool area 181 and the second pool area 183 along this gap is approximately equal to or higher than the high water line.

As illustrated in FIG. 8 , additional pool features may also be included. For example, a lagoon 187 may be in fluid communication with second pool area 183 and first pool area 181. The lagoon 187 may be a shallow area to permit the water to flow from the second pool area 183 back into the first pool area 181. As illustrated by the arrows, the water may be controlled through the second pool area 183 such that water is captured from the first pool area as waves are generated. The water then travels along the second pool area 183 to be recirculated back into the first pool area at a desired location. As illustrated in FIG. 8 , the desired location may be in the central area of the beaching area. As illustrated, in FIG. 10 , the water may be removed from the second pool area and reintroduced anywhere within the system. As illustrated in FIG. 11 , the water may be moved along the second pool area to be reintroduced in other areas of the pool such as at the lateral sides of the first pool area.

Exemplary embodiments of the wave generating device may include a beach area 188 adjacent the second pool area and/or lagoon and/or other water feature in which water may not reach and spectators may congregate. Other viewing areas 189 may be provided along other sides of the wave generating device, such as at lateral sides of the pool area 181.

Exemplary embodiments may therefore include a pool configuration in which wave energy flushes over a floor height corresponding to a desired water level (such as the low water line) into a second pool area. The second pool area may be of a deeper lagoon or trough. The second pool area(s) may be configured to absorb and dissipate the currents from the main pool or the pool used to create the waves. In an exemplary embodiment, the main pool and the secondary pool(s) may be fluidly connected through deep water channel, thereby maintaining the water levels of the main pool and secondary pool(s) at an equivalent height with no surge tanks or pumps required.

FIG. 9 illustrates an alternative pool configuration having a first pool area 191 and a second pool area 193 to dissipate energy created from wave 192. The main or first pool area 191 may include a low water line and a high water line as waves are generated and dissipate along the beaching area 195. A desired water line 194 may be selected in which the first pool area 191 and a second pool area 193 may be in fluid communication. This desired water line 194 may be at the low water line, below the low water line, or between the low water line and high water line, or combinations thereof along a length of the beaching area. This desired water line 194 may correspond to the highest elevation of a pool floor at a point between the first pool area and the second pool area. Similar to the illustration of FIG. 8 , a gap 196 may be formed between a portion of the first pool area 191 and the second pool area 193 along a length of the beaching area.

The embodiments of FIG. 9 may create a larger lagoon area at the beaching areas adjacent the lateral sides of the main pool 191 at opposing ends of the beaching area 195. The second pool areas may therefore comprise a slope that extends into the main pool area 191. The second pool areas 193 may then create a channel toward a center of the wave generating device to reenter the main pool area at a location in the middle of the beaching area.

In an exemplary embodiment, the wave generation device may include a deep water return channel 197. The deep water return channel 197 may fluidly couple one or more of the second pool(s) 193 with the main pool 191 away from the beaching area 195 of the main pool. As illustrated, the deep water return channel 197 goes under the beaching area 195 of the first pool 191 to fluidly couple to a floor of the first pool 191 adjacent the chambers or closer to the chambers than the beaching area.

Exemplary embodiments may therefore include wave generation devices having a first pool and one or more second pools. The first pool and one or more second pools may be configured such that wave energy from the first pool flushes over a desired water line or level and into the one or more second pools. As illustrated, two second pools may be used on opposing ends of the beaching area of the first pool. The second pool areas may thereafter deepen and provide water levels and return channels that may absorb and dissipate the water currents from the main pool. In an exemplary embodiment, the water may be returned back into the FIG. 10 illustrates an alternative pool configuration having a first pool area 111 and a second pool area 113 to dissipate energy created from wave 112. The main or first pool area 111 may include a low water line (L) and a high water line (H) as waves are generated and dissipate along the beaching area 115. A desired water line 114 may be selected in which the first pool area 111 and a second pool area 113 may be in fluid communication. This desired water line 114 may be at the low water line, below the low water line, or between the low water line and high water line, or combinations thereof along a length of the beaching area. This desired water line 114 may correspond to the highest elevation of a pool floor at a point between the first pool area and the second pool area. Similar to the illustration of FIG. 8 , a gap 116 may be formed between a portion of the first pool area 111 and the second pool area 113 along a length of the beaching area.

In the exemplary embodiment of FIG. 10 , the water from the one or more second pool(s) may be removed from the wave generating device and/or main pool 111. In this case, the water may be directed to a sump tank or other water feature, such as a lazy river or wading pool. In an exemplary embodiment, this other body of water may have a lower static water level to allow water to drain from the one or more second pools and/or the channels created thereby and into this other body of water. In an exemplary embodiment, the water from this other body of water may be pumped back into the main pool 111 and/or into the chambers 14. Flow rates and pump inlet locations may vary depending on the pool configurations and/or other body of water feature.

In an exemplary embodiment, the second pool area(s) 113 may be covered. The second pool areas comprise deeper channels that can capture the water as it overflows from the main pool 111 during a wave. The second pool area(s) may be covered by a perforated flooring such that water may pass there through, but patrons may walk over the top of the second pool areas. Therefore, all or portions of the second pool area(s) may not be used as part of the activity area of the water attraction. Instead, the second pool area(s) may be positioned underneath the beaching area.

Exemplary embodiments provided herein include a wave generating device in which wave energy may be flushed over a static water level divider and into one or more second pool areas. Currents may therefore be drained away to a sump or other water feature at a lower static water level than the main pool. Water may thereafter be pumped from the sump or feature back into the pool to maintain operational water levels.

FIG. 11 illustrates an alternative pool configuration having a first pool area 1111 and a second pool area 1113 to dissipate energy created from wave 1112. The main or first pool area 1111 may include a low water line (L) and a high water line (H) as waves are generated and dissipate along the beaching area 1115. A desired water line 1114 may be selected in which the first pool area 1111 and a second pool area 1113 may be in fluid communication. This desired water line 1114 may be at the low water line, below the low water line, or between the low water line and high water line, or combinations thereof along a length of the beaching area. This desired water line 1114 may correspond to the highest elevation of a pool floor at a point between the first pool area and the second pool area. In this exemplary embodiment, the desired water line 1114 is at or below the low water line for a portion of the length of the beaching area and is approximately equal to the high water line along another portion of the length of the beaching area. In an exemplary embodiment, the desired water line may be at the low water line and/or between the low water line and the high water line along an entire length of the beaching area such that a gap is not created between the first and second pools or a gap is only temporarily created between the first and second pools during the water generation.

As illustrated by the arrows of FIG. 11 , the water flow in the one or more second pools may be toward opposing lateral ends of the beaching area to the lateral sides of the main pool 1111. The second pools 1113 may extend along lateral sides of the pool 1111 and may be in fluid communication with the first pool 1111. In an exemplary embodiment, the bottom of the main pool 1111, either along a lower edge of the lateral side wall and/or through a floor of the pool 1111, may include grills or apertures to fluidly couple to the second pool(s) 1113. Water may be returned to the first pool 1111 through the lower portion or bottom of the first pool 1111.

Exemplary embodiments described herein may include a wave generating device in which wave energy may be flushed over a divider having a height at a desired water level and into a secondary pool. The secondary pool may comprise a channel having a covering. The covering may permit water to traverse the covering but may not permit a person or body part to traverse the covering. In an exemplary embodiment, the covering may conceal the channel within a beaching area of the first pool. In an exemplary embodiment, currents may be diminished in the channel. The channel and the first pool may be fluidly connected through openings at the pool bottom allowing the two bodies of water to maintain an equal water level without pumping. Users and patrons may also over the covering of the channel.

Exemplary configurations of systems and methods to dissipate wave energy and control currents within a main pool are provided herein. Illustrative combinations are provided by way of example only. Any exemplary feature may be used with any combination of other exemplary features. For example, any representative example may include shallow open pools that may act as wading pools or lagoons as second pool(s). Any representative example may include channels having coverings such that the second pool does not create an activity section. Any representative example may include a deep water return channel for coupling the second pool to a floor of the first pool. Any representative example may include one or more pumps to assist in fluid flow and moving water in a desired direction. Any representative example may have the first and second pool(s) in fluid communication during an entirety of a wave generation. Any representative example may have any configuration of the desired water line separating a top of the first pool from the top of the second pool to permit water from the first pool to overflow over the desired water line and into the second pool(s). For example, any representative example may position the desired water line below the low water line, approximately equal to the low water line, between the low water line and the high water line, or above the high water line, or any combination thereof along a length of the length between the first pool and one or more second pools.

Exemplary embodiments described herein may include a pool wave generator, having a pool area, and a plurality of chambers on one side of the pool area for releasing water into the pool area to generate a wave in the pool area. The pool area may include a first linear wall and the plurality of chambers are configured to release water into the pool area along an entire length of the first linear wall. The pool area may also include two lateral side walls extending from terminal ends of the first linear wall at an oblique angel.

Exemplary embodiments may also include a pool wave generator having a pool area and any method of generating a wave to propagate across the pool area. The pool wave generator may also include one or more second pool area(s). The first pool area and the second pool area may be separated by a divider having a height at a desired water level. The height of the divider may change along a length of the divider between the first pool area and the second pool area. The height of the divider may be at a low water height of the pool area during wave generation, at a resting water height of the pool area when waves are not being generated, at or above a low water height of the pool area during wave generation and below a high water height of the pool area during wave generation, and combinations thereof.

The second pool may be positioned across the pool area from the chambers. The second pool may be configured to create a channel for water to travel transverse across a length of the pool area and minimize an amount of water returned into the pool at an exit location of the water leaving the pool area after a wave. The second pool may be positioned to receive water exiting the pool area during a wave to minimize the direct return of the water back into the pool area.

The second pool may be in fluid communication with the first pool area through a deep channel positioned under a floor of the first pool area.

Water received in the second pool may be diverted into another water structure. For example, the other water structure may be a separate water activity area, such as a wading pool, a pool, a lazy river, or combinations thereof.

The second pool may comprise a channel. The channel may be configured to extend around a lateral side of the pool area. The channel may be configured to reintroduce water from the channel into the pool area at a bottom of the pool area.

The second pool may be covered, wherein the cover include perforations to permit fluid to flow there through but prevent a body part from traversing the covering.

FIG. 12 illustrates part of an exemplary floor bottom similar to FIG. 4 . As illustrated, the pool floor may include a return channel 1201 at the center of the pool. The return channel may be a floor contour to facilitate the current movements from the first and/or second pools as described herein. For example, an exemplary floor may include a continuous tapered area to permit smooth transition of the return water back into the pool. The return channel 1201 may facilitate a phenomenon similar to an eddy current. All or a portion of the return channel 1201 may be at a lower elevation relative to the pool floor on opposing lateral sides of the return channel at one or more locations and/or lengths.

FIGS. 13-19 illustrate exemplary features according to exemplary embodiments for managing currents using different configurations of return channels as described herein. These exemplary embodiments are illustrative only. The different components and configurations may be used in different combinations, and any feature, such as the shape, position, and/or creation of the channels using one or more walls, indentations, or as otherwise described herein may be used in any combination. Exemplary embodiments of select combinations are illustrative only. Exemplary embodiments of the return channels described herein may be used with any wave generating pool. As illustrated the wave generating pool may have a pool area 1304 with a plurality of chambers 1302 positioned at one end thereof. The chambers 1302 may release water into the pool 1304 at a bottom floor of the pool through openings 1306. The pool area 1304 may have a deep end adjacent to the chambers 1302, and may have a shallow end at an end of the pool away from the chambers. The pool floor may be tapered upward from the deep end toward the shallow end and/or may have sections of constant depth as described herein. As shown, the openings 1306 are positioned forward and separated by a gap from the forward wall of the chambers 1302, thus creating a passage from the chambers to the openings.

FIG. 13 illustrates an exemplary embodiment using shore and side channels, with a back circulation channel. This configuration may include a return channel behind the side angled wall. This configuration may also permit full circulation by including a back circulation channel in the gap between the front wall of the chamber and the back wall of the pool. This configuration brings together multiple exemplary configurations including multiple return channels, of a specific design.

As illustrates, the pool 1304 includes a shore return channel 1308. The shore return channel 1308 may be a portion of the shallow end of the pool floor that includes a deeper channel that captures water as it is pushed up the shore from a wave to reduce the amount of water that is then returned into the pool that may create eddy currents. The shore return channel 1308 may be positioned at, proximate to, and/or adjacent (either on the pool water side or the dry shore side) to the resting water level of the pool. The shore return channel may therefore be configured to capture much of the water before water is returned to the pool in a direction from the shallow end of the pool toward the deeper end of the pool.

As illustrated, the shore return channel 1308 may be in fluid connection to a side return channel 1310. As illustrated, the shore return channel 1308 may extend from the shallow end of the pool outward toward the lateral edges and directly couple and extend into the side return channel 1310. The side return channel may be positioned between the angled side wall 1314 of the pool and an exterior side wall 1312. The channel may have a variable floor depth (such as getting deeper toward the chambers) or may have a constant depth.

As illustrated, the side return channel 1310 may extend into and be in fluid communication with a back circulation channel 1318. The back circulation channel 1318 may be a passage between the back wall of the pool 1322 near the openings 1306 to permit water from the chambers 1302 into the pool 1304 and the front wall 1322 of the chambers 1302. As described herein, the chambers and the pool may include a gap in order to permit extension of the passage between the chamber 1302 and the opening 1306 for fluid flow management. The back circulation channel may use the space created by the gap and be positioned over the passage. As illustrated, the back circulation channel may be closed from the passage, the openings, the chambers, and/or the pool. The back circulation channel may be in fluid communication with the side return channel.

The return channels as illustrated may be in fluid communication with the pool 1304. As illustrated, the return channel may include an opening(s) 1316 between one or more of the return channels and the pool. As illustrated, the opening 1316 is positioned on an interior wall of the side channel 1310 in the angled side wall of the pool 1314. The opening may be at an end of the angled side wall 1314 at the deep end of the pool, adjacent the chamber 1302. The opening may be in the side wall, adjacent to the floor of the pool such that water is returned to the pool below the water level of the pool. The opening may extend upward on the wall to a height that is: less than the resting water height, less than or at three-quarters of the resting water height, less than or at half of the resting water height up the wall, or to another predetermined height in the wall.

FIG. 14 configuration is an exemplary embodiment using side channels. This configuration uses a larger surge tank style design behind angled walls. This configuration does not include the back circulation channel so that a full circulation channel is not created in this configuration. This configuration also provides a walkway along the side of the pool and over or adjacent to one or more channels and/or part of the pool.

As illustrates, the pool 1304 includes a shore return channel 1408. The shore return channel 1408 may be a portion of the shallow end of the pool floor that includes a deeper channel that captures water as it is pushed up the shore from a wave to reduce the amount of water that is then returned into the pool that may create eddy currents. The shore return channel 1408 may be positioned at, proximate to, and/or adjacent (either on the pool water side or the dry shore side) to the resting water level of the pool. The shore return channel may therefore be configured to capture much of the water before water is returned to the pool in a direction from the shallow end of the pool toward the deeper end of the pool. The shore return channel 1408 may have a variable depth such that the shore return channel 1408 is deeper adjacent to the sides of the pool. The shore return channel may therefore be shaped or configured to move water from in front of the pool to the sides of the pool to side return channel(s) 1410.

As illustrated, the shore return channel 1408 may be in fluid connection to a side return channel 1410. As illustrated, the shore return channel 1408 may extend from the shallow end of the pool outward toward the lateral edges and directly couple and extend into the side return channel 1410. The side return channel may be positioned between the angled side wall 1414 of the pool and an exterior side wall 1412. The channel may have a variable floor depth (such as getting deeper toward the chambers) or may have a constant depth. The side return channel 1410 may have a greater width as compared to FIG. 13 by creating a larger separation between the angled side wall 1414 and the exterior side wall 1412. The side return channel 1410 may extend behind the pool 1304 such that is overlaps with all or a portion of a side of the chamber.

The return channels as illustrated may be in fluid communication with the pool 1304. As illustrated, the return channel may include a plurality of opening 1416 between one or more of the return channels and the pool. As illustrated, the openings 1416 is positioned on an interior wall of the side channel 1410 in the angled side wall of the pool 1414. The openings may include coverings, such as gates so that one, more, or any combination of the openings 1416 may be closed, or their opening size may be changed or manipulated.

As illustrated, the side return channel 1310 may end at an end of the chambers. This configuration may therefore not include the back circulation channel 1318. The chambers 1420 may be fully enclosed as illustrated. The pool may also include a walkway 1418 from the shore along a side of the pool 1304. The walkway may extend in the gap between the front wall of the chamber and the back wall of the pool. The walkway 1418, as illustrated, may extend over a portion of one or more of the return channels, such as the shore return channel, the side return channel, the back circulation channel, or a combination thereof. As illustrated, the walkway 1418 extends over a position of the shore return channel 1408, and between the pool and the side return channel. The openings between the side return channel 1410 and the pool 1304 extend under the walkway 1418.

FIG. 15 configuration is an exemplary embodiment using side channels. This configuration provides another exemplary embodiment of a larger surge tank that may be positioned behind the angled side walls. This configuration uses a full circulation channel in the gap between the chamber(s) and the pool.

Similar to other configurations, this embodiment uses a side return channel 1510. The side return channel 1510 may be created between the pool side wall 1514 and an exterior side wall 1512. As illustrated, the exterior side wall 1512 is angled at a different degree than the pool side wall, creating a wedge shaped side return channel 1510. This configuration creates a larger surge tank. The side return channel 1510 may have a variable depth and/or may be of constant depth. Similar to the configuration of FIG. 13 , the side return channel 1510 is in fluid communication with a back circulation channel 1518. The back circulation channel may be positioned between the chamber(s) 1302 and the back wall of the pool and the opening(s) 1306 of the chamber into the pool. The back circulation channel, as illustrated, may be covered.

The exemplary embodiment illustrated in FIG. 15 illustrates a different shape and configuration of the shore return channel 1508. The shore return channel 1508 may extend from only a side of the pool and may extend toward the deeper portion of the pool. The shore return channel does not have to extend or traverse and entire length of the shore. As illustrated, the shore return channel is positioned in an area of the pool that is on a lateral side of the pool that is not directly in front of the chambers. As illustrated, the portion in front of the chambers may be the pool that is in contact with the wall creating a front of the chamber and the part of the pool that extends perpendicular to that wall. The area of the pool on the side of the pool that is not in front of the chambers toward the angled side wall may include the shore return channel. The shore return channel 1508 may extend or traverse the shore from the pool side wall 1514 for a length. The shore return channel 1508 may turn inward and extend along a length toward the chamber(s), toward the deeper end of the pool, and/or generally parallel to a portion of the pool side wall 1514, the exterior side wall 1512, or other measure of the side return channel 1510.

FIG. 16 illustrates an exemplary embodiment in which the side channel is created as a continuation of the pool bathemetry behind the angled wall, with the circulation channel in a gap between the chamber and the pool. The exemplary embodiment utilizes a mid-size angled wall.

In this configuration, a side return channel 1610 is created between an exterior side wall 1612 and the pool side wall 1614. The pool side wall 1614 may extend along a portion of the pool side, such that the entire pool side traverses the pool side wall 1614 and a portion of the exterior side wall 1612. The length of the pool side wall 1614 may be less than or equal to the length of the exterior side wall 1612. As illustrated, the pool side wall 1614 may be approximately half of the length of the pool side wall. The pool side wall 1614, may be 25% to 75% of the exterior side wall 1612. The pool side wall may extend to a height above the resting water height and/or the moving water height of the pool to create a barrier between the pool and the exterior side wall 1612 along the length of the pool side wall 1614. The pool may be in fluid communication with the side return channel 1610 in the area in which the pool side wall ends and the pool is in direct contact with the exterior side wall 1612. The end of the return side channel may be open to a portion of the pool.

FIG. 17 illustrates an exemplary embodiment using side channel in combination with a shore return channel and a pool return channel. In this configuration, the pool return channel is fluidly coupled to the shore return channel. This exemplary configuration also includes a side return channel that is a continuation of the pool bathemtry behind the angled wall. This configuration also includes a circulation channel in the gap between the chamber and the pool. This configuration includes a mid-sized angled wall.

Exemplary embodiments may include a shore return channel 1708. The shore return channel 1708 may traverse or extend across an entire length of the shore. The shore return channel 1708 may be covered (not shown), such as with a grating system or other covering to permit water flow therethrough. The shore return channel 1708 may be created as a channel in the pool floor that extends deeper in the floor to create a discontinuous indentation into the pool floor. The channel may also be a gradual depth change, thereby creating a continuous depth change. The channel may therefore be defined as a deeper portion of the pool in the shallow region of the pool, or having a shallow pool floor on opposing sides of the channel.

Exemplary embodiments may include a pool return channel 1728. The pool return channel may be a channel in the pool floor similar to the shore return channel. The return channel may be defined by a portion of the pool floor that is deeper than portions of the pool floor on one or both sides of the channel. The pool return channel 1728 may extend from the shore and/or from a portion of the shore return channel 1708 toward the chamber(s) and/or toward a deeper end of the pool. As illustrated, the pool return channel extends perpendicular from the front wall of the chamber(s) and is positioned generally in the middle of the pool, about an axis of symmetry of the pool. The pool return channel may be on a side or toward a side of the pool if the pool does not include two lobes or may be offset from a center of symmetry if the pool contains more than two lobes. The pool return channel may extend from a shallower portion of the pool and be at a depth approximately equal to the deepest portion of the pool. The pool return channel may extend from the shallower portion of the pool to the openings 1306 of the chambers in the pool floor. The pool return channel may extend from the shallower portion of the pool toward the deeper end of the pool, but may end before the openings 1306 in the pool floor in fluid communication with the chambers.

Exemplary embodiments may also include a combination of the shore return channel and the partial side wall configuration defining the side return channel. In this configuration as side return channel 1710 may be defined between a pool side wall 1714 and an exterior side wall 1712, similar to the side return channel describe din FIG. 16 . The shore return channel 1708 may be in fluid communication with the side return channel 1710 through the pool itself. The shore return channel 1708 may therefore be discontinuous from the side return channel 1710. The flow of water may therefore be controlled through the respective return channels. For example, water captured in the shore return channel 1708 may traverse the shore and return to the pool through the pool return channel 1728. Overflow water or other returning water may be captures in the side return channel 1710 that was not captured in the shore return channel. The side return channel 1710 may circulate the water through back circulation channel 1718.

FIG. 18 is a configuration in which the side channel is a continuation of the pool bathemetry behind an angled wall. The configuration does not include the pool return channel, but has a circulation channel under the mechanical room and also utilizes a shortened angled wall.

As illustrated, the pool may include a side return channel 1810. The side return channel may be created between a pool side wall 1814 and an exterior side wall 1812. Similar to the side channel of FIG. 14 , the separation distance between the pool side wall 1814 and the exterior side wall 1512 may be widened to overlap with a portion or all of the side of the chambers. Other shapes and configurations of the respective side walls are also contemplated herein. For example, the wedge shape of FIG. 15 may also be incorporated into an embodiment of a side channel similar to that of FIGS. 16-18 .

Exemplary embodiments of the side return channel 1810 may be in direct fluid communication with a back circulation channel 1818. The back circulation channel 1818 may permit fluid circulation between the back wall of the pool. The back circulation channel may be configured to permit fluid flow under a portion of the chambers, under a portion of the structure associated with the chambers (such as the plenum, the mechanical room, etc.), within the gap between the back of the pool and the chambers, behind the chambers, behind the passage between the chambers and the pool, and/or behind the chambers. As illustrated, the back circulation channel 1818 may be positioned under the mechanical room(s) associated with the chamber, as described in more detail with respect to FIG. 7 .

Any of the return and/or circulation channels described herein may be covered. For example, the space defining the channel may include a grating that includes openings to permit water to flow therethrough and/or may include a solid material. Exemplary embodiments, may include portions of the channel with solid covers while other portions have grated coverings. Entry into the channel may therefore be controlled and/or limited to select locations within the pool. Exemplary embodiments may include a cover to reduce the chance of debris and/or user's body parts and/or clothing from entering the channel. Exemplary embodiments may include other configurations of the channels described herein. For example, a channel may be created through piping within or under the floor structure. Access to a channel may be through one or more holes between the channel and the floor (including the shore) and/or wall of the pool.

FIG. 19 is a configuration in which the shore channel 1908 is in communication with a covered pool return channel 1928. The configuration does not include the side return channel, but may actually include any of the side return channels described herein. The FIG. 19 also includes a contoured entrance into the shore return channel for controlling/selecting water into the shore return channel 1908. The shore return channel may include grating along an entirety of the shore return channel. The shore return channel may include grating at only portions of the shore return channel, such as those corresponding to the floor contours on the lateral outside edges of the pool, the areas of the shore on opposing terminal ends of the area across from the chambers in areas of the pool extending beyond the terminal ends of the chambers in a lateral direction (parallel to the front wall of the chambers).

An exemplary embodiment may include a pool 1304 having a shaped floor bottom. The shaped floor bottom may be similar to that described with respect to FIG. 15 to create a shore return channel 1908 at lateral terminal end regions of the shore. In this configuration, the shore return channel 1908 may extend also toward the middle of the shore and extend across an entirety of the shore of the pool. The shaped bottom of the pool floor may include portions that have upwardly extending sloped floor 1911 from a deeper end of the pool (toward the chambers) to a shallow or shore end of the pool (toward the shore). Portions of the sloped floor 1911 may include regions of less slope or no slope so that indentations 1909 are created in the elevated sloped floor. The indentations 1909 may assist or control water floor in the pool. As described with respect to FIG. 15 , these indentations may be on outward lateral terminal end regions of the pool. The indentations 1909 may be in regions of the shore that is outside of the area directly in front of the chambers. The indentations 1909 may be in regions of the shore that are in portions of the pool beyond the end of the chambers. The indentations 1909 may have upwardly sloped floor 1911 regions on both sides of the indentation and/or the indentation 1909 may be directly up against a pool wall or edge.

Exemplary embodiments may include a pool return channel 1928 that is in fluid communication with the shore return channel 1908. As illustrated, the pool return channel is covered and includes first openings 1930 to permit water to flow from the shore return channel into the pool return channel. The pool return channel 19285 may also include second openings 1932 in a pool floor (or pool wall if return the return channel extends to or is part of the pool wall). The return channel may comprise pipes or other structure that may be embedded or under the pool floor. As illustrated, a portion of the return channel may be fully enclosed with a solid cover, while other portions of the channel may include openings to permit water to pass there through and be in fluid communication with the pool.

When reviewing current patterns within the pool, exemplary embodiments showed water turning back into the pool (and feeding the currents even more) before it was reaching the shore return channel(s). The water return may happen because the water naturally follows along the easiest path (path of least resistance); and due of the nature of the wave generation, the sequencing of the chambers was creating a small currents along the wall making the path along the wall the easiest path to follow. Exemplary embodiments therefore may use the side return channel as described herein. Exemplary embodiments may therefore end the pool side wall at the area the water returns to the pool.

Exemplary embodiments may also include pumps, turbines, flaps, or other water control devices to force the water to move into one or more of the return channels. The use of water control devices may influence the water flow path and redefine the easiest path for the water to follow (the return channel instead of the path along the wall).

Exemplary embodiments may therefore include any combination of pumps, turbines, flaps or other water control device in fluid communication in one or more of the return channels or in the pool in the space adjacent to the one or more return channels. Water from the pool may therefore be directed by the return channel and not along the wall. Exemplary embodiments may include fluid flow speed controls so that a user may be able to control the speed in the channel. Exemplary embodiments may therefore provide additional control over the currents in the pool.

Exemplary embodiments may include, as described herein, any combination of:

-   -   using a mouth of a side return channel on each side of the pool         to catch a maximum amount of energy,     -   a return channel going back behind the angle pool side wall,     -   a return side channel being connected either in between the         chambers and the pool or behind the mechanical room or in other         location to create a back circulation channel,     -   turbines and/or pumps added to the return channel to create a         new path of least resistance for the fluid flow,     -   turbines and/or pumps may be controlled so that they need not be         on all the time, but may be selectively turned on, such as to         kick start the flow circulation,     -   controller to permit variable speed in the return channel(s) to         tune the currents depending the wave size, wave frequency,         number of waves in a set, wave type,     -   use the equipment of the filtration to force the water in the         channel,     -   use the equipment of an existing lazy river, standing waves or         slides, or any attraction with a pump to power the return         channel,     -   and any combination thereof.
